Study Notes
Scapula Bony Landmarks
-
Acromion: Lateral extension of the scapula forming the highest point of the shoulder; serves as an attachment for the deltoid and trapezius muscles.
-
Coracoid Process: A small hook-like structure on the anterior surface of the scapula; provides attachment for several muscles including the pectoralis minor and short head of the biceps brachii.
-
Glenoid Fossa: A shallow depression on the lateral aspect of the scapula that articulates with the head of the humerus, forming the glenohumeral joint; crucial for shoulder mobility.
-
Superior Notch: A small notch located at the top of the scapula; allows passage for the suprascapular nerve.
-
Subscapular Fossa: A large concave area on the anterior surface; serves as the origin for the subscapularis muscle, which is involved in internal rotation of the humerus.
-
Spine: A prominent ridge that runs diagonally across the posterior scapula; provides attachment points for muscles and separates the supraspinous and infraspinous fossae.
-
Supraspinous Fossa: A shallow depression above the spine of the scapula; serves as the origin for the supraspinatus muscle, contributing to shoulder abduction.
-
Infraspinous Fossa: A larger concave area below the spine of the scapula; acts as the origin for the infraspinatus muscle, important for shoulder external rotation.
-
Lateral Border: The edge of the scapula closest to the humerus; an attachment point for the teres major and minor muscles.
-
Medial Border: The edge of the scapula facing the vertebral column; provides attachment for the serratus anterior muscle, which assists in scapular movement.
-
Superior Angle: The topmost point of the scapula; important for muscle attachments and helps define the movement of the shoulder girdle.
-
Inferior Angle: The bottom point of the scapula; acts as a key landmark for identifying the position of the shoulder joint and serves as attachment for the teres major muscle.
